FABRICATION OF VOICE CONTROLLED WHEEL CHAIR Abstract: Many disabled people usually depend on others in their daily life especially in moving from one place to another. For the wheelchair users, they need continuously someone to help them in getting the wheelchair moving. By having a wheelchair control system they become more independent. The aim of this research project is to design and fabricate a voice controlled wheelchair for physically disabled people. The wheelchair control system which employs a voice recognition system for triggering and controlling all its

movements.

It

integrates

a

microcontroller,

microphone,

voice

recognition processor, motor control interface board to move the wheelchair. By using the system, the users are able to operate the wheelchair by simply speaking to the wheelchair microphone. The basic movement functions includes forward and reverse direction, left and right turns and stop. The spoken words are linked to the voice recognition processor via a microphone attached closed to the user's mouth. It utilizes a PIC controller manufactured by Microchip Technology to control the system operations. It communicates with the voice recognition processor to detect word spoken and then determines the corresponding output command to drive the left and right motors. To accomplish this task, an assembly language program is written

and stored in the controller's memory. The voice controlled wheelchair runs successfully with a speed 1.21ft/s for 30kg load.
